The locations of the spots are defined in the rules, but why are they there and not somewhere else?
Start by understanding that we do NOT play Snooker on a Snooker table .. we play Snooker on an English Billiards table and the spots are placed for English Billiards players.
The layout for a full size table was a collaboration between John Thurston and the first actual billiards champion one Jonathan ( Edwin) Kentfield in the 1830's.
The spots on an English billiards table (which is the same table used for snooker) were originally placed based on mathematical and geometric principles to ensure standardized starting positions and provide a consistent basis for advanced shots like hazards and cannons. The specific positions are defined in the rules and were established in the 1830s as a collaboration between table manufacturer John Thurston and champion player Jonathan Kentfield.
The Geometric Rationale
The placement of the main spots allows for specific, predictable angles of play, which is crucial in a game that involves potting balls and using the rails for position.
The spots serve as precise reference points for:

The Geometric Rationale
The placement of the main spots allows for specific, predictable angles of play, which is crucial in a game that involves potting balls and using the rails for position.
- The Black Spot (Top Spot): This spot is located 12.75 inches from the face of the top cushion, centered along the table's length. It is precisely positioned such that a cue ball played from the center pocket to the black spot allows for a perfect "half-ball angle" for an in-off (losing hazard) into the top corner pocket.
- The Blue Spot (Center Spot): The blue spot is located at the exact center of the table. This is easily found by drawing lines diagonally from the center of each corner pocket, or by measuring the midpoint of the table's length.
- The Pink Spot (Pyramid Spot): This spot is located midway between the blue spot and the face of the top cushion. The red balls are racked in a triangle behind the pink spot for the start of a frame in snooker.
- The Baulk Line and "D": The baulk line is drawn across the table one-fifth of the length from the bottom cushion. A semi-circle ("D") is drawn on this line.
- The Brown, Green, and Yellow Spots: The brown spot is in the center of the baulk line. The green and yellow spots are at the intersections of the "D" and the baulk line. These spots are geometrically linked so that a shot from one of them to the pink spot creates a perfect half-ball angle for an in-off to a top corner pocket.
The spots serve as precise reference points for:
- Initial Setup: The spots ensure that every game starts from an identical, standardized position, guaranteeing fairness and consistency.
- Re-spotting Balls: When a colored ball is potted (in snooker) or a ball is fouled off the table, it is returned to its designated spot. This keeps the game flowing predictably.
- Strategic Play: The spots influence player strategy, as the high-value black and pink balls are positioned in critical areas (the "money end") of the table to encourage skillful break-building and positional play.
- Aiming Aids: While the spots on the felt are primarily for ball placement, the "sights" or diamonds on the table rails are also used by players to calculate angles for bank and kick shots using the "diamond system".
Use a string drawn taught between the centre of the fall of the corner pockets in an 'X' shape to find the Blue spot.
Similarly, string drawn taught between the corner pockets and the side pockets will find the Pink spot
